Understanding Diastolic Dysfunction (HFpEF), also known as Heart Failure with Preserved Ejection Fraction or Diastolic Heart Failure, is crucial for accurate clinical documentation and medical coding. This page provides information on diagnosing and documenting Diastolic Dysfunction, including key symptoms, diagnostic criteria, and relevant ICD-10 codes for healthcare professionals. Learn about the differences between Diastolic Dysfunction and systolic heart failure, and improve your medical coding accuracy for optimal reimbursement.
Also known as
Diastolic heart failure
Heart failure with preserved ejection fraction.
Combined systolic and diastolic heart failure
Heart failure affecting both contraction and filling.
Hypertensive heart disease with heart failure
Heart failure due to high blood pressure.
Left ventricular diastolic dysfunction
Impaired relaxation or filling of the left ventricle.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is EF < 40%?
Yes
Do NOT code as Diastolic Dysfunction. Consider other Heart Failure codes (e.g., HFrEF).
No

Coding HFpEF as unspecified heart failure without documenting diastolic dysfunction specifically.
Incorrectly coding hypertension or other comorbidities independently when they contribute to diastolic dysfunction.
Coding diastolic dysfunction based on symptoms alone without objective echocardiographic evidence.
Q: How can I differentiate between diastolic dysfunction and systolic dysfunction in patients presenting with heart failure symptoms?
A: Differentiating between diastolic and systolic dysfunction is crucial for effective heart failure management. While both present with similar symptoms like shortness of breath and fatigue, the underlying mechanisms differ. Systolic dysfunction involves impaired contractility and reduced ejection fraction (EF), whereas diastolic dysfunction, also known as heart failure with preserved ejection fraction (HFpEF), is characterized by impaired myocardial relaxation and filling during diastole, with a normal or near-normal EF. Key diagnostic features include echocardiographic assessment of diastolic parameters like E/A ratio, E/e' ratio, and left atrial volume. Consider implementing a comprehensive evaluation including patient history, physical exam, echocardiography, and potentially cardiac MRI or invasive hemodynamic assessment to accurately differentiate between these two conditions.

Q: What are the best evidence-based treatment strategies for managing diastolic heart failure in older adults with comorbidities?
A: Managing diastolic heart failure (HFpEF), especially in older adults with comorbidities, requires a multifaceted approach focusing on symptom control and addressing underlying conditions. Unlike systolic heart failure, there are currently no therapies proven to definitively reduce mortality in HFpEF. Treatment strategies often involve aggressive management of hypertension, diabetes, and other contributing factors. Diuretics can help manage fluid overload and alleviate symptoms like shortness of breath. Consider implementing exercise programs and lifestyle modifications tailored to the patient's functional capacity. Given the complexity of managing HFpEF in older adults, a personalized approach is essential.

Patient presents with symptoms suggestive of diastolic dysfunction, also known as heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure. Presenting complaints include exertional dyspnea, fatigue, and orthopnea. Physical examination revealed bibasilar rales, elevated jugular venous pressure (JVP), and an S4 heart sound. The patient's left ventricular ejection fraction (LVEF) is preserved, measured at greater than 50% via echocardiogram. Echocardiographic findings indicate impaired left ventricular relaxation and increased left ventricular filling pressures, consistent with the diagnosis of diastolic dysfunction. The patient's medical history includes hypertension and type 2 diabetes mellitus, both contributing risk factors for HFpEF. Differential diagnoses considered included chronic obstructive pulmonary disease (COPD) and valvular heart disease, but these were ruled out based on pulmonary function tests and further cardiac imaging. A treatment plan has been initiated, focusing on symptom management and addressing underlying comorbidities. This includes optimizing blood pressure control with antihypertensives, optimizing diabetic management, and diuretic therapy for fluid overload. Patient education was provided regarding lifestyle modifications such as sodium restriction and regular exercise. Follow-up appointments are scheduled to monitor symptom progression, treatment efficacy, and overall cardiac function. ICD-10 code I51.5 (Diastolic heart failure) is documented for this encounter.
